Alan Garner's latest novel Boneland features this as an important location. Drawing on its probable provenance as the place that Gawain meets the Green Knight in Hugh Massey's mediaeval poem, he has speculated that it will prove to be a major site of pre-historic rock art.

He discovered a 19th century document describing the descent of a miner into a crevice now hidden by earth movement. The miner reported seeing significant 'druidical remains'

Eternal Embrace

It could be humanity's oldest story of doomed love. Archaeologists have unearthed two skeletons from the Neolithic period locked in an eternal embrace and buried outside Mantua, Italy, just 25 miles south of Verona, the city where Shakespeare set the star-crossed tale of Romeo and Juliet.
After being found at the site where a factory is planned, people worldwide have speculated on the circumstances surrounding the couple's deaths. They are thought to have died young because they both had all their teeth intact. But beyond that, the skeletons are a mystery. Archaeologists announced Monday that they will move the entire block of earth the skeletons are resting in for further study and eventual display in a museum.

MAGIC AND MINING

The Alderley Edge Landscape Project has:

"tentatively confirmed the place of Alderley Edge at the dawn of metal working. The members of the project team believe that metal prospectors came to Alderley Edge at the beginning of the Bronze Age."

To view the site of the timber structure, walk north east along the embankment road from the southern end of Vauxhall bridge past the MI5 building. This is easy to spot as it looks exactly like a secret services building. Between Mi5 and the adjacent office building is a short road which leads to a ramp down into the river. This is the route used by the amphibious London 'Duck' tours.

Turn left at the bottom and walk under the bridge. On either side of the bridge in the embankment wall you will pass the outfalls of the river Effra. (Opposite further upstream on the north bank you will see an arched opening which is one of the outfalls of the river Tyburn). The structure is visible as a collection of timber stumps in the river just beyond the huge green glass St George's apartment development which is above you on your left.

The timbers can also be seen from above - again only at very low tide - from the raised embankment path to the south west of the bridge at the end of the St George's development - not where the information board claims.

Standing at Vauxhall cross - a large busy intersection of railway lines, an underground station, bus station a traffic roundabout and the home of MI5 - it is difficult to imagine that this is a site of some prehistoric significance. But take the ramp down to the relative peace of the Thames foreshore at low tide and things become clearer.

In 1999, following the discovery of neolithic axe heads by a member of the public, the remains of a bronze age timber structure were found - revealed by the eroding river bank. The site was partially explored further by Time Team in 2002 (Series Nine Episode 1) who found further axe heads and investigated one of the posts. The structure is considered to either be an early bridge across the river or possibly a jetty intended to connect the shore with an island which is now lost. The Thames at the period in question would have been much shallower and many such Eyots - raised gravel mounds - exist under the water. Bronze spears were also discovered - apparently intentionally placed into the river bed.

This location is topographically significant - it is the point where the tidal Thames turns - where salt water meets fresh and the place where the rivers Effra, on the south bank and Tyburn, on the north, (both now subterranean) empty into the greater river. These outfalls can also be seen at low tide.

As these rivers were once navigable, it is likely that the area was a focus of some activity and it appears that several ancient routes converged upon it - as their contemporary equivalents still do. A southern projection of the Roman Watling street reaches the river on the bank north of Vauxhall.

the author attributes Kennington lane as being on the route of a raised pre-roman trackway between the site of the original Kennington settlement (on a gravel hill above the Thames flood plain) and Vauxhall. The timber bridge / jetty would then be a continuation of this route - linking the Kennington settlement either with the 'holy' island or the north bank of the Thames.

There are two rows of about twenty stumps - leaning inwards and giving an estimated jetty width of about four meters. Each is approximately 400mm in diameter.

The structure may be soon gone because now exposed, it is subject to erosion - although Time team established that the posts are deeply grounded. The mystery is at least as much as how timber can survive for thousands of years - particularly in a situation like this.

''standing in Walbrook, on the south side of this High Street, neere unto the Channell, is pitched upright a great stone called London Stone, fixed in the ground very deep, fastened with bars of iron, and otherwise so stronlglie set that if cartes do runne against it through negligence the wheeles be broken, and the stone itself unshaken. The cause why this stone was there set, the verie time when, or other mermorie thereof, is there none. "

The Sweet Track is an ancient causeway in the Somerset Levels, England. It is one of the oldest engineered roads known and the oldest timber trackway discovered in Northern Europe. Tree-ring dating (dendrochronology) of the timbers has enabled very precise dating of the track, showing it was built in 3807 or 3806 BC. It has been claimed to be the oldest road in the world.
The track was discovered in the course of peat digging in 1970, and is named after its discoverer, Ray Sweet. It extended across the marsh between what was then an island at Westhay, and a ridge of high ground at Shapwick, a distance close to 2,000 metres (about 1.24 miles). The track is one of a network of tracks that once crossed the Levels.
Built in the 39th century BC, during the Neolithic period, the track consisted of crossed poles of ash, oak and lime (Tilia) which were driven into the waterlogged soil to support a walkway that mainly consisted of oak planks laid end-to-end. Curves at the bases of the poles show that they were from coppiced woodland.
Due to the wetland setting, the components must have been prefabricated elsewhere.
Most of the track remains in its original location, and several hundred metres of it are now actively conserved using a pumped water distribution system. Other portions are stored at the British Museum, London, while a reconstruction can be seen at the Peat Moors Centre near Glastonbury.
Since the discovery of the Sweet Track, it has been determined that it was actually built along the route of an even earlier track, the Post Track, dating from 3838 BC and so 30 years older.

In case it isn't obvious, this enclosure and the adjacent hut circle are a short walk from the Kingston Russell stone circle.

Walk down the hill towards Little Bredy. There is a fence with two gates in it. Take the right hand and walk straight ahead. The hut circle (5m diameter) is the raised green doughnut in front with the similarly shaped but larger (15m diameter) enclosure a little further on and to the left.

The entrances of both (like the Grey Mare and possibly the circle) are aligned South East

They are beautifully sited on the slope of this amazing valley and, with the stone circle, grey mare and other adjacent tumuli, form part of a little Neolithic sequence - and presumably once, a linked community

The stone here is a real mixture of Oolite, flint and quartz. Pick a pebble up and you can see the sparks dance in the sunlight.

This newish exhibition at The Museum of London has an amazing collection of mesolithic, neolithic, bronze and iron age artefacts - together lots of very good information on the periods and the history of the Thames Valley and the area of the city in particular.
